Just convert it:

PdBm=20*log(V/Vo)

where Ro=50 ohm,  Pm = 0.001 W, thus Vo=sqrt(0.001*50)= 0.224 V

so for Pdbm = -136:

V=Vo*10^(-136/20)
...

V = 35nV or 0.035uV!

Subject: [Elecraft] K3 test results?


I have been trying to figure out where the
K3 will fall in the Sherwood receiver test data chart.

http://www.sherweng.com/table.html

The info on the Elecraft web page for the K3 is
different, and I am not sure how one compares...

K3 sensitivity is listed as -136, while the Sherwood page shows microvolt's.
Would that correspond to the Sherwood noise floor?
What about the preamp?
